Okay so the probability of drawing a blue bean is

8 / 29 = .276

29 is the total number of jelly beans

When we have replacement, we do not reduce the number of total jelly beans, so the probably of drawing blue stays the same.

But to find the probability of drawing a blue two times in a row, we must square the probability .

(.276) • (.276) = 0.076

Your answer is 7.6% !

If your have any questions, leave a comment! I hope I helped :)

A store that sells skis buys them from a manufacturer at a wholesale price of $63. The store’s markup rate is 50%. a. What price
Reptile [31]

a. The store charges $94.5 for the skis

b. 150% of the original price is the final price

Step-by-step explanation:

The given is:

  • A store that sells skis buys them from a manufacturer at a wholesale price of $63
  • The store’s markup rate is 50%

We need to find at what price the store charges its customers for the skis and

what percent of the original price is the final price

∵ The store buys the skis at $63

∴ The cost price of the skis = $63

∵ The store’s markup rate is 50%

- Find the amount of 50% of the cost price

∵ 50% of 63 = \frac{50}{100} × 63 = 31.5

∴ the store's markup the cost of the skis by $31.5

- To find the selling price add 31.5 to the cost price

∴ The selling price of the skis = 63 + 31.5 = $94.5

a. The store charges $94.5 for the skis

To find what percent of the original price is the final price divide the final price by the original price then multiply the quotient by 100%

∵ 94.5 ÷ 63 = 1.5

∵ 1.5 × 100% = 150%

∴ The final price is 150% of the original price

b. 150% of the original price is the final price

Delia measured her bathtub to be 2 meters long. What is an equivalent measurement?
allochka39001 [22]


An equivalent measurement to 2 meters is 200 cm. Since 1 meter is equivalent to 100 cm, multiply both of them by two. So, your answer is - 2 meters is equivalent to 200 cm.

Hope it helps :)

Use differentials to approximate the change in the volume of a cube when the side is decreased from 8 to 7.99 cm. (in cm3)
Firlakuza [10]

Answer:

  -1.92 cm³

Step-by-step explanation:

The formula for the volume of a cube in terms of side length is ...

   V = s³

Then the first-order approximation of volume for a small change ∆s in side length is ...

  V(s +∆s) ≈ V(s) + V'(s)·∆s

and the change in volume is ...

  ∆V ≈ V(s +∆s) -V(s) = V'(s)·∆s

The derivative V'(s) is ...

  V'(s) = 3s²

so the change in volume for s = 8 cm and ∆s = -0.01 cm is ...

  ∆V ≈ 3s²·∆s = 3(8 cm)²(-0.01 cm) = -1.92 cm³
